The AMoRE (Advanced Mo-based Rare process Experiment) project is a series of experiments that use advanced cryogenic techniques to search for the neutrinoless double-beta decay \mohundred. work being carried out by an international collaboration researchers from eight countries. These searches involve high precision measurements radiation-induced temperature changes and scintillation light produced in ultra-pure \Mo[100]-enriched \Ca[48]-depleted calcium molybdate...
Abstract Studies of Li 2 O–MoO 3 , Cs MoO 4 –MoO and Na phases have helped us to develop several new crystals such as Mo 5 O 17 13 7 10 6 11 36 grown by a Czochralski method. Syntheses the polycrystalline materials are discussed based on thermogravimetric analysis (TGA) differential scanning calorimeter (DSC) crystals’ structures reported X‐ray powder diffraction (XRD) analysis. Luminescence properties from room temperature K studied exciting crystal with 280 nm light emitting diode (LED)....
The COSINE-100 experiment has been operating with 106 kg of low-background NaI(Tl) detectors to test the results from DAMA/LIBRA experiment, which claims have observed dark matter. However, since background crystals used in is 2–3 times higher than that DAMA detectors, no conclusion regarding claimed observation could be reached. Therefore, we plan upgrade current next phase, COSINE-200, by using ultra-low detectors. basic principle was already proved commercially available Astro-grade NaI...
Abstract The AMoRE collaboration is preparing for the second phase of experiment, AMoRE-II, which will exploit a 100 kg Mo isotopes to search neutrinoless double beta decay from isotope. Most be contained in lithium molybdate (Li 2 MoO 4 ) crystals, act as absorbers cryogenic calorimeters coupled MMC (metallic magnetic calorimeter) sensors. detector array have total mass approximately 200 with hundreds modules. Hence, considerable effort has been taken optimize crystal terms performance and...

Abstract The annual modulation signal observed by the DAMA experiment is a long-standing question in community of dark matter direct detection. This necessitates an independent verification its existence using same detection technique. COSINE-100 has been operating with 106 kg low-background NaI(Tl) detectors providing interesting checks on signal. However, due to higher backgrounds crystals used relative those for DAMA, it was difficult reach final conclusions. Since start data taking 2016,...
The Center for Underground Physics (CUP) at the Institute Basic Science (IBS) has been conducting two major experiments, COSINE experiment dark matter search and AMoRE neutrinoless double beta decay search. is using NaI:Tl scintillation crystals studying 100Mo based such as CaMoO_{4}(CMO), Li_{2}MoO_{4}(LMO), etc. In order to develop ultra-pure we have built a clean-environment facility minimize external contamination during crystal growth. Here, report growth internal background levels of...

AMoRE searches for the signature of neutrinoless double beta decay $^{100}$Mo with a 100 kg sample enriched $^{100}$Mo. Scintillating molybdate crystals coupled metallic magnetic calorimeter operate at milli-Kelvin temperatures to measure energy electrons emitted in decay.
